Yes thats right, they are intended just for use in files, though they  
can also be used to encapsulate the setup for one view to apply to  
another view.

Renderers can have a user interface. This is currently only used for  
plugin renderers but I don't think there is a restriction to them  
only. The Microspot renderer uses it though many of the calls it  
currently uses have been deprecated by Apple. The application just  
asks the renderer to interact with the user and so it has to have  
platform specific code to bring up a dialog or whatever and store the  
selected preferences in its own prefs file.

If it simply an on or off preference, then you could have one  
renderer with it on an another with it off.
